Would someone please be able to explain how:
Well, it looks like a simple Arithmetic Series:
[F + L] x N/2 =Sum, where F=first term=100, L=Last term=5,000, N=number of terms=50
[100 +5,000] x 50/2 =127,500 total sum of apples for 50 bushels.
10 x100 =1000% increase in industrial production.
is dumb
Hello HighSchoolCalculus,
What is you problem ?
I have been off line for most off today but I do not see a question of yours here ://
Can I help you with anything?
Oops! That's the volume rotated about the x axis!
Volume rotated about the y axis is \(\int_0^9\pi x^2 dy \rightarrow \int_0^9 \pi ydy \rightarrow 81\pi/2\)
Volume of "disc" at x is \(\pi y^2dx\)
So overall volume = \(\int_0^3\pi x^4dx \rightarrow \pi 3^5/5 \rightarrow 243\pi/5\)
How long will you have to wait unil your account is worth $50,000?
E+A is already in simplest form.
Which one do you want solved?
l'm not familiar with some symbols in the first part.
Here's the second part though :D
\((pi)^18)^(1/2)/2 = 14904.549666723105
You really don't want to help. l'm pondering on dropping my class due to the difficulty of this segement. My love for math has died.
lf you want to rationalize that... just do a sweet move (something my teacher calls this method):
Just multiply the numerator and denominator by the denominator over the denominator (otherwise just 1)
\(1/\sqrt2513*(\sqrt2513/\sqrt2513)\)
Your result:
\(\sqrt2513/2513\)
well that's a little embarrassing, i've just disregarded distrubtion...
thankyou for your help and also your quick responce.
good luck with your slopes, wish I could help
136000(1+0.055)^5 = 177746.560871675
There's a calculator here for a reason.
Anyways what you have so far is pretty good. Derivatives by the definiton are a bit of a pain l'd rather not go back to.
The 11 came from x = 4 and f(4).
All that means is you plug in four for x into that funciton you were given.
f(4) = 2(4)+3
See?
Anymore questions? Just ask! (Not like l'm doing anything other than tearing my hair out from slope fields and Euler's method.)
compute least-squares regression line for predicting y from x given the following summary statistics. \(\begin{array}{|lcl|} \hline \bar{x} &=& 6 \\ s_x &=& 3 \\ \bar{y} &=& 1350 \\ s_y &=& 101 \\ r &=& 0.7 \\ \hline \end{array}\)
\(\begin{array}{|rcl|rcl|rcl|} \hline y &=&\alpha+\beta x & \alpha &=& \bar{y}-\beta\bar{x} & \beta&=& r\cdot \frac{s_y}{s_x} \\ && & && & \beta&=& 0.7\cdot \frac{101}{3} \\ && & && & \beta&=& 23.5\bar{6} \\ && & \alpha &=& 1350-23.5\bar{6} \cdot 6 & \\ && & \alpha &=& 1208.6 \\ y &=&1208.6+23.5\bar{6} x \\ \hline \end{array} \)

\(\begin{array}{|rcll|} \hline && C(9,6) \\ &=& C(9,9-6) \\ &=& C(9,3) \\ &=& \frac{9}{3}\cdot \frac{8}{2}\cdot \frac{7}{1} \\ &=& 3\cdot 4\cdot 7 \\ &=& 84 \\ \hline \end{array}\)
30(1+0.08/12)^3 =30(1.0066667)^3 =30 x 1.0201336296 =$30.60
FV = PV[1 + R]^N
37,961.66 = 5,000[1 + R]^15 divide both sides by 5,000
7.592332 = [1 + R]^15 take the 15th root of both sides
1 + R =7.592332^(1/15)
1 + R =1.1447 subtract 1 from both sides
R =1.1447 - 1 x 100
R = 14.47%

and if it goes on forever i think it would be infinity or 1

Hi random person.
I like helping people here but it is always nice when people, such as yourself, express their appreciation.
Thank you :)
Why don't you join and become less random ? :D
We'd like that :))
Cscθ=-2.1625
\(csc(x)=-2.1625\\ \frac{1}{sin(x)}=-2.1625\\ \frac{1}{-2.1625}=sin(x)\\ sin(x)=\frac{1}{-2.1625}\\ x=asin(\frac{1}{-2.1625})\\\)
asin(-1/2.1625) = -27.543876784605 degrees
\(x\approx 180+27.5+360n \qquad x=360-27.5+360n\qquad n\in Z\\ x\approx 107.5+360n \qquad or \qquad \;x\approx332.5+360n\qquad \qquad n\in Z\\\)
